Technical Field

[0001] The utility model relates to the technical field of plate testing, in particular to a plate impact resistance testing fixing frame. Background Art

[0002] Sheets are flat rectangular building materials in standard sizes, used in the construction industry as wall, ceiling or floor components. They also refer to forged, rolled or cast metal sheets. Before they are used, the performance of the sheet needs to be tested, and impact resistance testing is one of them.

[0003] The existing plate impact resistance test device is usually unable to fix plates of different sizes and shapes when using the plate, and it is inconvenient to perform impact resistance tests on various plates. Therefore, we propose a plate impact resistance test fixing frame; Utility Model Content

[0004] The utility model aims to solve the defect that the prior art cannot meet the needs of fixing plates of different sizes and shapes, and proposes a plate impact resistance test fixing frame.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A plate impact resistance test fixture, comprising a base, four support seats arranged at equal intervals at the bottom of the base, a groove opened at the top of the base, and four slide slots opened at equal intervals at the top of the base. The plate impact resistance test fixture also includes:

[0007] Four fixing components, the four fixing components are arranged on corresponding slide grooves, and the four fixing components are used to clamp and fix the same plate;

[0008] The impact-resistant test component is arranged on the base, and is used to test the impact-resistant performance of the plate.

[0009] In a possible design, the fixing assembly includes a limiting ring, which is slidably connected to the inner wall of the corresponding slide groove, a first threaded rod is fixedly connected through the limiting ring, the top of the first threaded rod extends to above the base and is fixedly connected to the first support block, the top of the first support block is fixedly connected to a support column, the top of the support column is rotatably connected to the second support block, the second support block is threadedly connected to the second threaded rod, the top of the second threaded rod is fixedly connected to a handle, and the bottom of the second threaded rod is located between the first support block and the second support block and is fixedly connected to the first fixed block.

[0010] In a possible design, two rotating blocks are fixedly installed on one side of the base, the two rotating blocks are rotatably connected to the same second support rod, the second support rod is rotatably connected to the telescopic rod, the bottom of the telescopic rod is threadedly connected to a fixing bolt, and the fixing bolt is threadedly connected to the base.

[0011] In a possible design, the impact resistance test component support includes a second fixed block, which is fixedly arranged on the telescopic rod. One side of the second fixed block is fixedly connected to the first support rod. The first support rod is passed through and fixedly connected to an electromagnet, and a pressure ball is magnetically adsorbed on the bottom of the electromagnet.

[0012] In one possible design, a limiting rope is fixedly connected to the bottom of the electromagnet, a through hole is opened through the pressure ball, the limiting rope passes through the pressure ball, and a blocking ball is provided at the bottom of the limiting rope. The limiting rope is used to limit the position of the falling pressure ball, and the blocking ball is used to limit the position of the pressure ball when it falls and bounces up, so as to prevent it from bouncing around and accidentally injuring staff.

[0013] In a possible design, a buffer pad is installed in the groove, and the buffer pad is used to buffer the impact of the pressure ball.

[0014] In the present application, the base is first placed flat, and then the telescopic rod is bent to stand up at a 90° angle between the telescopic rod and the base, and then the fixing bolt is tightened to fix the telescopic rod, and then the height of the telescopic rod is adjusted, and then the four second support blocks are rotated to move the second support blocks away from the top of the first support blocks, and then the plate to be tested is placed on the four first support blocks, and then the second support blocks are rotated to be above the first support blocks, and then the handle is turned to press the first fixed block downward to fix the plate.

[0015] During the process, if the plate is of irregular shape, loosen the nut on the first threaded rod under the base, and then slide the limit ring in the slide groove to move the position so that the irregular plate can be placed on the four first support blocks, and then tighten the nut on the first threaded rod to fix the first threaded rod to the base, and then turn the four handles to fix the first fixed blocks to the plate, and then pass the pressure ball through the limit rope and place it on the bottom of the electromagnet, and adsorb the pressure ball on the electromagnet through the magnetic force of the electromagnet, and then start the switch to make the electromagnet lose its magnetic force. After losing the magnetic force of the electromagnet, the pressure ball freely falls and hits the plate, and the impact resistance of the plate is tested by the impact force brought by the free fall of pressure balls of different masses.

[0016] In the utility model, the plate impact resistance test fixing frame is provided with four movable first support blocks, so that irregular plates can be placed and fixed, and the impact resistance test of various plates can be achieved;

[0017] In the utility model, the plate impact resistance test fixing frame can limit the falling position of the pressure ball by limiting the pressure ball with a limiting rope, and prevent the pressure ball from bouncing up and accidentally injuring the staff after falling;

[0018] In the utility model, four movable first support blocks are provided so that irregular plates can be placed and fixed, thereby achieving the purpose of testing various plates.

An impact resistance test component is arranged on the base 1, and the impact resistance test component is used to test the impact resistance performance of the plate.

[0026] The fixing assembly includes a limiting ring 301, which is slidably connected to the inner wall of the corresponding slide groove 3, and a first threaded rod 302 is fixedly connected to the limiting ring 301, the top of the first threaded rod 302 extends to the top of the base 1 and is fixedly connected to the first support block 303, the top of the first support block 303 is fixedly connected to a support column 304, the top of the support column 304 is rotatably connected to a second support block 305, the second support block 305 is threadedly connected to a second threaded rod 306, the top of the second threaded rod 306 is fixedly connected to a handle 308, the bottom of the second threaded rod 306 is located between the first support block 303 and the second support block 305 and is fixedly connected to the first fixed block 307, the limiting ring 301 sliding on the inner wall of the slide groove 3 allows the first support block 303 on the limiting ring 301 to move according to different templates, and when testing irregular plates, the plates can also be fixed to facilitate testing.

[0027] The impact resistance test component support includes a second fixed block 401, which is fixedly arranged on the telescopic rod 4, and a first support rod 402 is fixedly connected to one side of the second fixed block 401. An electromagnet 403 is fixedly connected to the first support rod 402, and a pressure ball 404 is magnetically adsorbed on the bottom of the electromagnet 403. By setting the electromagnet 403 to magnetically adsorb pressure balls 404 of different weights, disconnecting the power supply and allowing the pressure ball 404 to fall freely to generate an impact force acting on the plate, an experiment to test the impact resistance of the plate is achieved.

[0028] The bottom of the electromagnet 403 is fixedly connected with a limit rope 405, and a through hole is opened in the pressure ball 404. The limit rope 405 passes through the pressure ball 404. A blocking ball is provided at the bottom of the limit rope 405. The limit rope 405 is used to limit the position of the falling pressure ball 404.
